Background: In recent years, international ranking systems have been used by diverse users for various purposes. In most of these
rankings, different aspects of performance of universities and research institutes, especially scientific performance, have been
evaluated and ranked. In this article, we aimed to report the results of research ranking of Iranian universities of medical sciences
(UMSs) based on some international indicators in 2015.

Methods: In this study, after reviewing the research indicators of the majority of international ranking systems, with the participation
of key stakeholders, we selected eight research indicators, namely research output, high-quality publications, leadership, total
citations, citations per paper in 2015, papers per faculty member and h-index. The main sources for data gathering were Scopus,
PubMed, and ISI, Web of Science. Data were extracted and normalized for Iranian governmental UMSs for 2015.

Results: A total of 18023 articles were indexed in 2015 in Scopus with affiliations of UMSs affiliation. Almost 17% of all articles
were published in top journals and 15% were published with international collaborations. The maximum h-index (h-index = 110)
belonged to Tehran University of Medical Sciences. The average paper per faculty member was 1.14 (Max = 2.5, Min = 0.13). The
mean citation per published articles in Scopus was 0.33.

Conclusion: Research ranking of Iranian UMSs can create favorable competition among them towards knowledge production.
